As per Moderator tools privileges delete link is visible to any 10K+ users. They can't delete directly. They have to vote to delete to delete the post. So they get this message when click on delete link:

Vote to delete this post?

While diamond moderators or OP (of the post) can directly delete it. So this message should not be shown. Instead the should be something like this:

Are you sure? Do you want to delete this post?

So probably this is a bug.

I don't know what message do diamond moderators get when they click on delete link.
